Reliability, Availability, Maintainability (RAM) Analysis
Reduces the time that critical systems are non-operable. INEL has a package of methods and software tools for RAM Engineering, most of which are not licensed to nuclear utilities (Yet! -- ways will be found to handle the potential conflict of interest, as this work is chiefly done for the NRC.) In the meantime, there's nothing to stop application by utilities to non-nuclear facilities.

RELAP5 Simulator is an exception, in that there is widespread use by utilities (the utility user's group costs $5K/year) as well as by the NRC and groups around the world. Developed at INEL, it predicts thermal hydraulic behavior in power plants (transient multiphase, multi-component flow and energy transfer in complex piping and vessel systems, with additional modules for pumps, turbines, valves, etc.). It has even been used to model blood flow, and is a later version of EPRI's RETRAN code.
